February 28, 2018 – The announced they are collaborating to integrate Haystack tagging and Brick data modeling concepts into the proposed ASHRAE Standard 223P for semantic tagging of building data.

ASHRAE Standard 223P: "Designation and Classification of Semantic Tags for Building Data” provides a dictionary of semantic tags for descriptive tagging of building data including building automation and control data along with associated systems.

By integrating Haystack tagging and Brick data modeling concepts with the upcoming ASHRAE Standard 223P, the result is intended to enable interoperability on semantic information across the building industry, particularly in building automation.

This unified effort is aiming at a formally standardized application data modeling solution which can be implemented in various ways. For example, it will be able to be used for exchanging data over established communication protocols like the Haystack web services or BACnet, or being applied on data stored in databases and cloud applications. The first public review of the initial draft of 223P is envisioned for late 2018. Ultimately, ASHRAE Standard 223P is intended to be adopted as an ISO standard.

Aside from the engineering and automation efficiency improvements machine-readable semantic descriptions of data will provide, a single global standard will enable broader interoperability among applications.
